The way to look at this in EVERY situation is that you never subtract. You always add the additive inverse. For any number
, the additive inverse is
. Just remember that if
So, if you have (-16) on one side and you want to get rid of it, add the additive inverse of (-16), namely 16.
Similarly, you also NEVER divide. You always multiply by the multiplicative inverse. If
is any number other than zero, then the multiplicative inverse is
. So if you had
, you would multiply both sides by
which is the multiplicative inverse of the
coefficient on the variable.
